Ojective To enhance the ability of diagnosis and therapy for occult indirect inguinal hernia. Methods Surgical exploration was performed for patients highly suspected with occult indirect inguinal hernia based on clinical manifestations and physical examinations in the initial stage. At present, herniography was used to confirm the diagnosis. High ligation of the hernial sac, non-mesh methods of open groin hernia repair or tension-free inguinal hernia repair was performed for the patients. Results Forty-four cases were given surgical exploration in the initial stage and 41 cases were confirmed and treated by operation. Misdiagnosis was found in 3 cases and surgical exploration revealed no sign of disease. Relapse occurred in two cases within 5 years. Nineteen out of 30 patients were confirmed by herniography in the last five years and operated on. There was no false-positive herniogram in this series. Follow-up evaluation of the patients showed disappearance of preoperative symptoms. Groin hernia has not recurred so far. Conclusions The ability of diagnosis for occult indirect inguinal hernia can be enhanced by herniography. Blind surgical exploration can be reduced. Herniography is a safe, reliable and practical diagnostic procedure.

Objective: To compare the efficacy of paroxetine and amitriptyline in the treatment of primary fibromyalgia syndrome.Methods:46 out- and in-patients with primary fibromyalgia syndrome were randomized to two groups and treated respectively with amitriptyline 25mg~50mg per day and paroxetine 10mg~20mg per day. The Visual analogue scales(VAS) was used to evaluate the efficacy and adverse effects were recorded at baseline, month 1 and month 3.Results:In both groups pain was alleviated with statistical significance after 1 month of treatment. However the efficacy of amitriptyline and paroxetine was not statistically significant at different time points. The occurrence of adverse effects in paroxetine group was less than in amitriptyline group and the difference was statistically significant, especially dry mouth and palpitation.Conclusion:Paroxetine is as effective as amitriptyline in the treatment of primary fibromyalgia syndrome but with a better safety profile.

Inflammatory bowel disease(IBD)is an autoimmune disease and its etiology has not yet been clarified. Dysregulated immune responses resulted from complex interactions among genetic factors,intestinal flora and environmental cues have been considered as the etiology of IBD. Recently,the relationship between Th17 cells and IBD has become a hotspot of study,and more and more studies showed that Th17 cells and their related cytokines regulated by intestinal flora contributed to the pathogenesis of IBD. This article reviewed the role of Th17 cells and intestinal flora in the pathogenesis of IBD.

Objective To study the effects of siltuximab on the interleukin-6 (IL-6)/signal transducer and activator of transcription 3 (Stat3) signaling pathway in ovarian epithelial carcinoma.Methods (1) Expressions of IL-6 in ovarian cancer patient specimens were assessed by immunohistochemistry.(2) Expression of phosphorylation Stat3 (pStat3) protein in siltuximab and IL-6 treated SKOV3 cell lines was determined by western blot, and expression levels of Stat3-induced bcl-XL,MCL-1, survivin, in siltuximab treated SKOV3/TR and CAOV3/TR cells lines were also determined by western blot.(3) Real-time image analysis was used to study the nuclear translocation of pEGFP-Stat3 fusion protein in ovarian cancer cell line SKOV3-pEGFP-Stat3 treated with siltuximab and IL-6.(4)Paclitaxel sensitivity in siltuximab treated SKOV3/TR and CAOV3/TR cell lines were assessed using the methyl thiazolyl tetrazolium (MTT).The 50% inhibiting concentration ( IC50 ) was defined as the paclitaxel concentration required to decrease the A490 value to 50%.Results ( 1 ) There were significantly difference in IL-6 staining density and the positive rate of IL-6 protein stained among the metastatic, and drug-resistant recurrent tumors,and matched primary tumors [69%(18/26)] vs.77% (20/26)vs.23% (6/26), P＜0.05].(2)A clear increase in Stat3 phosphorylation levels was observed in the IL-6-treated SKOV3 cell lines as compared to the SKOV3 cell lines.When the IL-6-treated SKOV3 cells were incubated with siltuximab with a range of concentrations of 0.001,0.01,0.1, 1.0 and 10 μg/ml, there were trends toward reduced pStat3 expression in the treated cell lines.Compared without treatment with siltuximab, the expression of the anti-apoptotic proteins MCL-1, bcl-XL and survivin in SKOV3/TR and CAOV3/TR cell lines were significantly decreased after treated with siltuximab.(3) In resting cells, the majority of pEGFPStat3 was cytoplasmic until the addition of human IL-6, which promptly induced the translocation of fluorescent Stat3 molecules to the nucleus.Exposure of cells to siltuximab with a range of concentrations of 0.001, 0.01,0.1, 1.0 and 10 μg/ml, followed by an incubation in IL-6 significantly reduced pEGFP-Stat3 nucleocytoplasmic translocation.(4) MTT cytotoxicity assay demonstrated that siltuximab increased paclitaxel-induced cell death and partially overcame paclitaxel resistance.Treated with siltuximab ( 1 and 10 μg/ml) ,the paclitaxel IC50 value of siltuximab in SKOV3/TR (0.49, 0.19 μg/ml) and CAOV3/TR (0.0010, 0.0008 μg/ml) cells were significantly lower than those in untreated cells (0.71,0.0021 μg/ml;all P ＜ 0.05).Conclusions These results demonstrated that siltuximab effectively block the IL-6 signaling pathways, which .Blockage of IL-6 signaling may provide benefits for the treatment of ovarian cancer.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.

In this study, metabolism of nobiletin in rats was studied using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). As a result, seven major metabolites were found in bile, urine and serum of rats. Three phase I products were assigned to be demethyl and di-demethyl products, and other four phase II products were assigned to be glucuronic and sulfonic conjugates. The four phase II metabolites were reported for the first time. Among the metabolites found in the present study, the glucuronic conjugates of demethyl-nobiletin played a predominant role in the metabolic pathway, indicating that its potential role for glucuronidation-related factors, such as gene polymorphism, drug-drug interaction, etc., in changing the active and toxic effect of nobiletin and that it should be paid more attention in further development.

Objective To observe the effects of histone deacetylases inhibitor (HDACi) on cognitive performance and cerebral tau phosphorylation in transgenic mice coexpressed five familial Alzheimer' s disease mutations (5XFAD).Method The total 12 5XFAD-CC and 12 wild type (WT) mice were administrated with suberoylanilide hydroxamic acid ( SAHA,n =7) and vehicle ( n =5 ),respectively.The cognitive performance was assessed by Y-maze and Morris water maze.The protein levels of acetylated α-tubulin,total tau and phosphorylated tau and phosphorylated glycogen synthase kinase-3β (GSK3β) were determined by Western blotting.Results SAHA ameliorated learning and memory deficits in 5XFAD-CC mice (39.10％ ±2.25％,t =2.688,P =0.0312 for total numbers of entrance in novel arm; 26.81％ ±0.78％,t =3.271,P =0.017 for time spending in novel arm; F =5.936,P =0.045 for hidden platform;31.70％ ±4.21％,t =2.317,P =0.049 for probe trial).Administration of SAHA significantly increased acetylated α-tubulin in hippocampus of WT and 5XFAD-CC mice (26.42％ and 29.64％,respectively).Additionally,SAHA attenuated tau-pSer396,tau-pSer404 and tau-pThrThr231 in hippocampus of 5XFAD-CC mice (24.22％,48.98％ and 26.95％,respectively). Moreover,hippocampal phosphorylated GSK3β was markedly reduced in SAHA-treated 5XFAD-CC mice (31.29％). Conclusion SAHA may improve cognitive performance in 5XFAD-CC mice, which is associated with its significant effects on the phosphorylation of tau and GSK3β.
